In this work, vertically aligned 2D SnS2 nanoflakes were grown directly on FTO-glass substrates using a scalable close space sublimation (CSS) method. Scanning electron microscopy revealed that our nanoflakes contain vertical tapered structures with high aspect ratios and high density of exposed edges. They exhibit an indirect bandgap of 2.28eV and are excellent photoabsorbers. Photoanodes consisting of these nanoflakes were synthesized and measured in aqueous pH7 buffer containing Na2SO3 as hole-scavenger. Photocurrents up to 4.5mAcm-2 were obtained at 1.23 V vs. RHE under simulated sunlight.
